Mobil Pegasus 1107
Mobil Pegasus 1107 is a premium gas engine oil developed for modern high-output, low-emission four-cycle gas engines operating under demanding conditions. It is formulated using advanced base oils and additive technology to deliver outstanding oxidation stability, nitration resistance and long service life while maintaining strong protection across a wide range of applications.
One of the key advantages of Mobil Pegasus 1107 is its extended oil life capability. The formulation offers excellent resistance to oxidation and nitration, helping maintain oil performance over longer service intervals and reducing maintenance frequency and operating costs.
Mobil Pegasus 1107 also provides excellent engine cleanliness. Its advanced detergent-dispersant system helps control the formation of carbon and varnish deposits, ensuring clean pistons, rings and combustion areas while maintaining engine efficiency and reliability over extended periods.
Another important benefit is its strong anti-wear protection. The oil helps protect critical engine components such as liners, pistons and valve trains, reducing wear and scuffing even under high load, high temperature and high pressure conditions.
Mobil Pegasus 1107 also features a higher sulphated ash level and strong alkalinity reserve compared to lower ash variants. This helps provide improved protection against corrosive combustion by-products, particularly in high BMEP engines, while supporting long-term engine durability.
The product is suitable for use in turbocharged and naturally aspirated gas engines, including lean-burn and stoichiometric designs, as well as cogeneration systems and engines operating on natural gas or low levels of sour gas. It is particularly suited for high-performance engines requiring extended drain intervals and strong deposit control.
Mobil Pegasus 1107 meets key OEM requirements including MAN M 3271-5, Jenbacher approvals, Caterpillar Energy Solutions TR 2105 and Bergen engine approvals, making it suitable for demanding industrial and power generation applications.
Physical characteristics include a kinematic viscosity of approximately 113 mm²/s at 40°C and 13.1 mm²/s at 100°C, with a viscosity index of around 112. Mobil Pegasus 1107 has a density of approximately 0.88 g/cm³ at 15.6°C, a flash point of approximately 261°C and a pour point of approximately −18°C. It also features a sulphated ash content of approximately 0.65% and a base number of approximately 7.3 mg KOH/g, supporting reliable performance in demanding gas engine applications.
